PATENT OFFICE NEW YORK, N. 'Y., ASSIGNOR TO LOLA MARSALLE, OF

n'nooxmm, NEW YORK DEVICE TO PREVENT PI'ICIHING AND ROLLING OF SHIP CABINS, ETC.

Application filed July 20;

The invention relates to-a devicewhich prevents pitching and rolling by means of a large solid ball rotating in a cup the inside of the cup, or the outside of the sphere; or

both may have ball bearings to allow easy movement; two semi circular hoops prevent rotation about the vertical axis.

' The invention is especially adapted to ships. After the freight is loaded into the ships hold the hatchway is of no use. This device with its series of nonpitching, nonrolling cabins may be set up in this space and used while at sea. It can be readily removed when the ship reaches port. This device'may be set up into the ship when it is built in place of the usual cabins, etc. One form of the invention as applied to ship cabins is illustrated in the accompanying drawing, in which Fig. 1 is a vertical section of the entire arrangement while it is attached to the ship to allow passengers to enter or leave the cabin; Fig. 2 is a vertical section of the entire arrangement after having been disconnected from the ship and while the ship is rolling toward the starboard; Fig. 3 is a detailed "ertical section of the main device; Fig. 4 is a plan view of the legs or standards; Fig. 5 is a detailed plan view ot the lower stopper; Fig. 6 is a detailed vertical sect on of the lower stopper and the balanclng weights; Fig. 7 is a detailed vertical section of the device which automatically'starts the motors which move the balancing weights.

The cup 1, which may or may not contain ball bearings 2, is supported by its legs or standards 3, which are secured to sides of the coaming 4, by means of cable 5, or ledge 6, or both; in the cup 1, is located the solid ball which may or may not have bearings. The ball is prevented from going out of the cup by a removablecollar 26. The movement of ball 7 about its own perpendicular axis which would otherwise wedge the cabins against the coamings is prevented by two semi circular bands 8 and 9; band 8 the ends of which are fastened to the opposite sides of the hub 10, and which passes through the lower set of rollers lllocated at right angles in rectangular block 12; band 9 the ends of which are fastened to the under side of the 1928. Serial No. 294,155.

cabin 13 and which passes thru the upper set of rollers 14. These bands may also be made slotted and a pin with or without bearings in its sides placed thru the slots instead of the method just described.

The upper cabin 13 is framed into the ball 7. Cabins 15 and 16 are suspended from cabin 13 by means of members 14. 29 is an accordion curtain to keep the elements out of the hold.

In order to effect a comfortable entrance and exit of passengers the cabins are connected to the ship and roll and pitch with it, this is accomplished by lowering upper stopper 15 which has ratchet teeth along its side into well 17 and also by means of lower stopper Fig.5 located on underside of cabin 15 consisting of a cam 17 which forces rod 18 into well 19 located in coaming 21. These cabins are then released by raising the upper stopper 15 and turning cam 17 which causes spring 20 to ex and pulling rod 18 out of well 19. The s ip will then roll and pitch independently of the cabins which are maintained level, by the device.

To prevent the cabins from deviating from a horizontal plane and to an occasional unequal distribution of the load in them, balancing weights 27 move on track 22 suspended from and running the length of the under side of cabin 15. The wei hts 27 reviously referred to are moved by and or y motor 28. Fig. 7 shows a simple means of, starting the motor 28 automatically; on the underside of cabin 16 is fastened a ball 23 which fits into a circular plate 25 which may contain ball hearings in its cup shaped hub. This plate always remains level, due to its construction.

The underside of cabin 16 has a series of contact .points 24 placed circul arly above plate 25.

When cabin 16 tilts in any direction the contact points 24 come into contact with plate 25 which causes the motor to move the weight until the cabin becomes level thus breaking the contact and stopping the motor.

I claim:

1. In self levelling ship cabin the/combination with a series of shlp cabins suspended 100 one above the other of an apertured ball fastened to the underside of one of said ship cabins, an apertured standard, a socket element in said standard provided with ball races on its circumference and in which saidball is fitted for universal angular movement to preserve the level of said ship cabins, means passing through said apertured ball and standard to lock said ball and standard together, a general arcuate form rigidly fastened to the underside of said ship cabin, and a similar band rigidly fastened to said standard at right angles to the previously mentioned band, said bands passing through roller bearings set at right angles to each other in a bearing block to prevent the rotation of said ship cabins about its vertical axis, asliding rod positioned underneath of said cabins, a spring connected with said sliding rod, a cam for actuating said sliding rod against the tension of said spring so as to force said rod into an opening in the ship structure so as to lock said cabin to said ship structure, means for actuating said cam so as to allow said spring to force said rod back to its original position.

2. In a structure such as described the combination of a unitary structure comprising a plurality of cabins having one cabin at the upper part, means for mounting said structure within an opening in the deck of the ship, said means permitting the structure to have a universal movement independent of the ship, comprising a ball and socket connection between said upper cabin and the deck, positioned substantially on a level with said upper deck, the portion of the structure below said upperdeck being substantially greater in length than the portion above same, whereby said lower portion will operate as a counterbalance for the structure.

3. In a structure such as described the combination of a unitary structure comprising an upper cabin, a base borne by standards movable relative to said structure and supporting the same, the base being positioned within opening in the upper deck of the ship and supported thereby, a ball and socket connection positioned between the floor of said cabin and said base, said structure having a lower portion greater in len th than said upper cabin and extending tiirough an opening in another deck and capable of counterbalancing the structure, the ball and socket forming the sole means of support for the structure and the balance of the structure below said upper cabin being suspended from said upper cabin.

4. In a structure such as described the combination of a unitary structure insertable within openings in a plurality of decks of a ship, said structure comprising a plurality of cabins, one projecting above the decks and one below one deck, the portion below the upper cabin being greater in length than the upper cabin, a supporting member secured to one deck, a ball and socket connection between the upper cabin and said support, whereby the upper cabin is supported by said one support and the balance of the structure suspended therefrom, and is capable of counterbalancing the upper cabin.

5. In' a structure of the kind described the combination of a supporting structure having a plurality of decks or floors separated one from the other with a swinging structure having an upper and a lower chamber, a ball and socket connection between one of said chambers and one of said decks or floors for supporting the entire swinging structure, the balance of the swingin structure being sus pended from said chamber and extending beyond the ball and socket connection and be ing greater in length than the other portion, 7

said extending portion also extending through another deck or floor, whereby the swinging structure will be counterbalanced and-one of the decks or floors will limit the amount of independent movement of said swinging structure.
